Depression and anxiety in children Flashcards
(33 cards)
Depression: Epidemiology
Prevalence:
0.2% 5 – 10 year olds (pre-pubertal children)
2% 11 –15 year olds (adolescents)
The rise in adolescence seems to be more closely linked to pubertal status than to chronological age.
Sex ratio: equal in pre-adolescent boys and girls, but twice as common in girls in later adolescence.
Depression: Aetiology
Depression runs in families.
Depressed children are more likely than children with other psychiatric disorders to have parents or siblings who are themselves depressed.
Conversely, parents with depression are more likely to have depressed children.
Twin studies suggest moderate heritability, but this has not been replicated in adoption studies.
There is preliminary evidence that a genetic loading for depression may sometimes act by increasing a young person’s vulnerability to adverse life events ‘a gene–environment interaction’.
Core symptoms of depression
Persistent and pervasive sadness or unhappiness.
Loss of enjoyment of everyday activities (Anhedonia)
Irritability
Depression: Associated symptoms
Negative thinking and low self-esteem
Hopelessness
Unwarranted ideas of guilt, remorse or worthlessness
Suicidal thoughts or thoughts of death
Lack of energy, increased fatigability, diminished activity,
Difficulty concentrating, forgetfulness
Appetite disturbance (decrease or increase)
Sleep problems (insomnia or hypersomnia).
Depression: Clinical presentation
Young people tend to present initially with behavioral or physical complaints which may obscure the typical depressive symptoms seen in adults.
Irritability or cranky mood
Chronic boredom or loss of interest in previously enjoyed leisure activities (for example, dropping out of sporting activities, or dance and music lessons)
Social withdrawal or no longer wanting to “hang out” with friends
Avoiding school
Decline in academic performance.
Change in sleep-wake pattern (for example, sleeping in and refusing to go to school).
Frequent unexplained complaints of feeling sick, headaches, stomach-aches.
Development of behavioral problems (such as becoming more defiant, running away from home, bullying others).
Abusing alcohol or other substances.
Diagnosis: Major depressive episode
Core symptoms
Some associated symptoms (usually four should be present)
Pervasiveness (symptoms must be present every day, most of the day)
Duration (for at least two weeks)
Symptoms must cause impairment in functioning or significant subjective distress, and
Symptoms are not the manifestation of the effects of a substance or another medical condition.
Symptoms should not be due to another mental disorder.
Depression: Classification
One major depressive episode with no manic, hypomanic or mixed episodes = major depressive disorder, single
Two or more major depressive episodes but no manic, hypomanic or mixed episodes = major depressive disorder, recurrent.
Depression: Classification 2
Those with milder symptoms may meet the diagnostic criteria for dysthymia or adjustment disorder with depressed mood.
Dysthymia involves chronic mild symptoms for at least one year (as opposed to the two years stipulated for adults).
An adjustment disorder can be diagnosed if the symptoms occur shortly after an identifiable stressor (within three months according to DSM-V) and do not outlast the stressor by more than six months.
Depression: Severity
Mild:
5 depressive symptoms (at least 1 core).
Mild impairment in functioning.
Moderate:
6-7 symptoms (at least 1 core).
Considerable difficulty in continuing with school work, social and family activities.
Severe:
More than 7 depressive symptoms.
Hallucinations or delusions (psychotic depression).
Severe impairment in most aspects of functioning.
Significant risk of suicide.
Depression: Comorbidity
Over 50% of depressed children in epidemiological samples have at least one other psychiatric disorder as well
Anxiety disorder
Disruptive behavioural disorder
Learning disorder,
Rate of comorbidity is often even higher in clinic samples.
Depression: Diff. Diagnosis
Normal sadness, including normal bereavement reactions.
Misery can occur as just one feature of another psychiatric disorder, without the additional affective, cognitive and behavioural features needed to diagnose a true depressive disorder.
Mental disorder due other medical conditions e.g., hypothyroidism
Substance or medication induced depressive disorders
Disruptive mood dysregulation Disorder
Mx: Psychosocial (CBT and IPT)
CBT:
The cognitive restructuring component of CBT is designed to alter negative cognitions, improve self-esteem and enhance coping skills.
behavioural activation component is designed to increase involvement in normal and rewarding activities.
Social skills training, problem solving treatment and remedial help with specific learning problems may also be offered.
Stress reduction interventions - school liaison, supportive individual therapy and family interventions.
E.g , if a bullied child becomes depressed, then tackling the bullying may be enough to cure the depression as well.
In more severe cases, however, it is necessary to treat the depression itself,
Mx: medication
Meta-analyses – tricyclic antidepressants are little or no better than placebos for children and adolescents.
Serotonin reuptake inhibitors (SSRIs), particularly fluoxetine, are better than placebos at treating child and adolescent depression (especially severe depression).
Mx: Fluoxetine
Fluoxetine is the only antidepressant approved by the US Food and Drug Administration (FDA) for the treatment of depression in children.
However, there are also concerns that SSRIs increase the risk of self-harm or suicide.
Analyses of reported adverse effects do suggest an increase in suicidal ideation and threats, with few attempts and no completed suicides.
In the light of reported levels of adverse effects with different SSRIs, the British Government guidelines do not support the use of SSRIs other than fluoxetine for depressed children or adolescents.
Tx approach: Mid
support and stress reduction are often sufficient.
TX approach: Moderate
Step 1: Support and stress reduction
Step 2: if fail- CBT or IPT ( If fail)
Step 3: if fail: Trail of SSRI- Fluoxetine
Tx approach: Severe
Combination – combined pharmacological and psychological treatment.
Admission to an in-patient unit is indicated when there is severe suicidality, psychotic symptoms, or refusal to eat and drink.
Single episode - Continue successful therapy for about six months after
symptomatic remission in order to prevent early relapse
Prognosis
An adjustment disorder with depressed mood usually lasts a few months and does not typically recur after the stressor is resolved.
Major depressive episodes often last six to nine months and commonly recur.
Dysthymia typically persists for several years; dysthymic individuals are at a high risk of major depressive episodes.
Someone with ‘double depression’ (that is, major depressive episodes superimposed on dysthymia) is particularly likely to experience recurrent major depressive episodes
Prognosis: Adult outcome
Depression occurring in adolescence is often followed by depression in adult life,
Also predicts a roughly six-fold increase in adult suicide rates.
Depression occurring before puberty is less likely to lead to adult depression.
Anxiety Dos in children
Separation anxiety Disorder ( SAD)
Generalised Anxiety Do ( GAD)
Social phobia
Specific phobia
Panic Do
Agoraphobia
Common features
Core feature- avoidance- overt:specific situations, places, or stimuli. Subtle: hesitancy, uncertainty, withdrawal. Difference is the trigger
accompanied by affective components of fearfulness, distress or shyness.
Expectation of a threat- something bad is going to happen
All anxiety involve -anticipation of threat, in the form of worry, rumination, anxious anticipation, or negative thoughts
physical complaints -reflecting heightened arousal- headaches, stomach aches, nausea, vomiting, diarrhoea, and muscle tension.
Epidemiology
Prevalence: around 5% of children and adolescents meet criteria for an anxiety disorder during a given period in Western populations (Rapee et al, 2009).
Gender: often F>M
Age of onset:
Animal phobias – early childhood -6-7 years
Separation anxiety Do – early to mid-childhood- 7-8 years
GAD– late childhood- 10-12 years
Social anxiety disorder – early adolescence -11-13
Panic disorder – early adulthood (around 22-24 years)
Risk factors
Anxiety runs in families.-
Anxious children are more likely to have parents with anxiety disorders and
adults with anxiety disorders are more likely to have anxious children.
Temperament - inhibition, shyness (mostly seen 2-5yrs of age)
Common features of inhibition include:
Withdrawal in the face of novelty.
Slowness to warm up to strangers or peers.
Lack of smiling.
Close proximity to an attachment figure.
Lack of talk.
Limited eye contact or “coy” eye gaze.
Unwillingness to explore new situations.
Genetic – 30-40% heritable
-serotonin transporter gene (5HTTLPR) explored
Environmental stressors (home, school, environment)
Parenting and family factors- anxious parents.
- overprotection, intrusiveness and, negativity
Negative consequences
Academic
Social
